So, it works for fixnums but not for bignums?
The code must always work for valid indata, if it
doesn't, even for a single such case, the optimization breaks
the algorithm and will be removed.
Maybe we can duplicate it and remove the declaration in one
of them. So we would have one Fibonacci to test the speed of
fixnums, and one for bignums. In the fixnums one, the
declaration would still be legal.
